Article Details

Title: Biostimulants induced changes in root phenomics and soil microbial dynamics in rice under wetland conditions
Journal: Plant Physiology Reports
Volume/Pages: 31 (2026), 98–110
Publication Date: 28 January 2026
Authors: B. Kamali, B. Aparna, B. Rani
Study System: Rice (var. Uma) under acidic wetland conditions
Design: Pot experiment (2023) + Field experiment (2024)
Location: Department of Soil Science and Agricultural Chemistry, College of Agriculture, Vellayani, Thiruvananthapuram, India
Treatments: RDF combined with multiple biostimulants (seaweed extract, humic substances, PGPR mixes, Pseudomonas, Panchagavya, etc.) plus control and RDF-only comparison
Core Focus: Root phenomics, microbial dynamics, and metabolite profiling under biostimulant treatments

Novelty

The study is novel in its integrated root–microbe–metabolite approach under wetland acidic rice systems. Key novel aspects include:

  • Simultaneous evaluation of root architecture, microbial colonization, and biochemical metabolites rather than yield alone
  • Use of Scanning Electron Microscopy (SEM) to visualize microbial biofilms and root colonization patterns under biostimulant influence
  • Focus on phenolic acid modulation (p-coumaric, vanillic, syringic acids) as functional biochemical indicators
  • Comparative assessment of multiple biostimulant classes (organic, microbial, and humic-based) under identical agronomic conditions
  • Demonstration of PGPR mix superiority across both controlled (pot) and field environments, strengthening translational relevance

Overall, the novelty lies in linking belowground biological processes to biostimulant-driven performance in acidic wetland rice ecosystems.

Impact

The study has moderate to high agronomic and soil biological impact:

  • Demonstrates clear improvement in root system architecture (25–45% gains)
  • Shows strong enhancement of microbial activity and endophytic colonization
  • Identifies PGPR mix-1 as a consistent high-performing input across environments
  • Provides evidence that biostimulants can reduce reliance on sole chemical fertilizer dependency (RDF integration rather than replacement)

Scientific impact:

  • Strengthens the concept of plant growth–promoting rhizobacteria (PGPR) as multifunctional biostimulants
  • Contributes to understanding of microbe-induced root phenomics modulation in rice

Agronomic impact:

  • Potential to improve productivity in acidic wetland soils, which are typically constraint-prone systems

Originality

The originality is relatively high in methodological integration:

  • Combines phenomics + microbiology + metabolomics + microscopy in one experimental framework
  • Moves beyond conventional agronomic response studies (yield-focused)
  • Introduces biofilm visualization evidence in rice roots under field-relevant biostimulant application
  • Evaluates multiple biostimulant categories in a comparative, standardized experimental design

However, conceptually:

  • PGPR and humic/seaweed biostimulants are already well studied
  • The originality lies more in integration and multi-parameter validation, not in discovering entirely new mechanisms

Experimental Rigor

Strengths:

  • Two-stage validation: pot + field experiments
  • Completely Randomized Design with three replications
  • Inclusion of control and RDF baseline comparison
  • Multi-dimensional assessment: root traits, microbial counts, SEM imaging, metabolite profiling
  • Quantitative microbial enumeration (log CFU g⁻¹) adds robustness

Limitations:

  • Limited information on statistical significance details (e.g., ANOVA outputs, p-values not shown in abstract)
  • No mention of multi-location field validation, which limits generalizability
  • PGPR mix composition not fully detailed in summary (potential reproducibility constraint)
  • Duration limited to single season field validation

Overall rigor: moderate to strong, with good experimental layering but limited long-term validation.

Sustainability Impact

The study strongly supports sustainable agriculture principles:

  • Reduces dependency on chemical inputs through biological enhancement of nutrient uptake efficiency
  • Improves soil biological fertility (microbial abundance and diversity)
  • Enhances plant resilience in acidic stress-prone wetland soils
  • Supports eco-friendly rice production systems aligned with low-input agriculture

Key sustainability contributions:

  • Promotes bio-based soil health restoration
  • Enhances nutrient cycling via microbial activation
  • Potential reduction in fertilizer runoff and soil degradation risks

Sustainability rating: high relevance for sustainable intensification of rice systems

Applicability

Practical applicability is strong in specific agroecological contexts:

Highly applicable to:

  • Acidic wetland rice ecosystems (common in parts of South India and Southeast Asia)
  • Farmers already using RDF systems who can integrate biostimulants
  • Organic-integrated or low-input rice farming systems

Moderately applicable to:

  • Neutral or alkaline soils (requires validation)
  • Large-scale mechanized farms (depends on cost and availability of PGPR formulations)

Constraints:

  • Commercial availability and standardization of PGPR mix-1 may limit immediate adoption
  • Requires farmer training for optimal application timing and dosage
  • Long-term consistency across seasons not yet established

Article Details

  • Title: Diagnostic reference levels in interventional neuroradiology: a scoping review
  • Authors: Marvin Grech, Francis Zarb, Reuben Grech, Neville Calleja & Paul Bezzina
  • Published: 25 March 2026, European Radiology
  • Type: Open-access review article
  • Scope: Evaluates literature on diagnostic reference levels (DRLs) in interventional neuroradiology (INR), including both diagnostic (cerebral angiography) and therapeutic procedures (stroke thrombectomy, aneurysm coiling, AVM/AVF embolisation).

Novelty

  • Provides a comprehensive synthesis of DRLs specifically in INR, an area with limited consolidated data.
  • Highlights the wide variability in reported DRLs, which had not been systematically compared before.
  • Emphasizes methodological differences (percentile choice, procedure grouping, inclusion criteria), which are rarely discussed in prior reviews.

Impact

  • Raises awareness of dose variability in INR procedures, which is directly relevant to patient safety and radiation exposure optimisation.
  • Serves as a reference for hospitals and regulatory bodies to develop or refine local DRLs.
  • Supports the broader movement towards standardising radiation dose monitoring in interventional radiology, improving compliance with European and international radiation protection guidelines.

Originality

  • Unlike single-center or national studies, this is a scoping review covering 39 studies across multiple countries, offering a global perspective.
  • Combines data on multiple INR procedures, not just diagnostic angiography or one therapeutic intervention.
  • Offers critical evaluation of methodologies used to derive DRLs, not just reporting numbers.

Experimental Rigor

  • Rigorous systematic search strategy using multiple databases: SCOPUS, Web of Science, PubMed, and ProQuest.
  • Clear inclusion criteria for studies reporting DRLs in both diagnostic and therapeutic INR procedures.
  • Extracted detailed parameters (PKA, FT, RAK, sample size, statistical approaches).
  • Limitation: Being a scoping review, it does not perform meta-analysis or standardised statistical comparison; focuses on summarisation rather than quantitative synthesis.

Sustainability Impact

  • Indirectly promotes sustainability in healthcare by:
    • Encouraging radiation dose optimisation, reducing unnecessary patient exposure.
    • Highlighting best practices in procedural efficiency, which can lower resource use (fluoroscopy time, contrast agent use).
  • Standardised DRLs could lead to less procedural waste and more efficient interventional radiology workflows.

Applicability

  • High clinical relevance:
    • Can guide radiologists, medical physicists, and hospitals in setting or updating local DRLs.
    • Useful for regulatory bodies and professional societies when developing national or international dose guidelines.
  • Can inform training programs for INR practitioners to be aware of typical dose ranges.
  • Supports harmonisation across institutions, aiding multicenter studies and quality improvement programs.
